		Title: Average speed of a rip on a long balloon ID #: HS-53-3 © copyright: Loren M. Winters Medium: 35mm negative Description: Sound triggers at either end of the balloon discharge 2 flash units to illuminate the rip at different instants. The disk (dia.=10.5 cm), rotating at 51.7 Hz, can be used to measure the time interval to obtain the average speed of the rip. Technique: double-burst flash Category: Speed	Title: Speed of a BB ID #: HS-13-17 © copyright: Loren M. Winters Medium: 35mm negative Description: Two flash units, independently triggered by sound, illuminate a speeding BB, a meter stick, and a disc rotating at 50.4 Hz. This provides enough information to calculate the speed of the BB. Technique: double-burst flash Category: Speed
		Title: Speed of rip on round balloon ID #: © copyright: Loren M. Winters Medium: 35mm negative Description: The average speed of the rip in this balloon can be found using the time interval and distance between the eyes of the figure (0.98 cm). The rip is traveling much faster than sound. Technique: double-burst flash (interval = 0.098 ms) Category: Speed	Title: E's on a turntable ID #: SP-21-17 © copyright: Loren M. Winters Medium: 35mm negative Description: letter E's show blur proportional to speed on 33 rpm turntable Technique: ambient lighting (shutter = 1/8 second) Category: Speed
